GEM SETTING.

Application flied May 4, 1928. Serial No. 275,055.

This invention relates to gem settings, and the primary object thereot is to provide a setting which has novel means for enabling same to be connected to a chain or chains or the like, especially in connection with bracelets or various other means which may be employed for the purpose of securing the gem to the person.

A. further object, of the invention is to provide a gem setting in which the means for connecting same to a chain or the like also provides a drainage opening for drainage of the acid employed in plating the setting.

Still further, the invention aims to provide a novel gem seat.

In the drawings Figure 1 is a top plan view of the invention in the first stage of the manufacture;

Figure 9 is a like view in the second stage;

Figure 3 is a like View of the complete setting;

Figures 4, 5 and 6 are sections on lilies qti, 55 and 66 of Figures 1, 2 and 3, and

Figure 7 is a bottom plan view of a moditied form of the invention.

In proceeding in accordance with the present invention, a blank is first formed as illustrated in Figures 1 and 4 and is of cupshape having a bottom, and a right angular rim E2, serrated at its top edge 3, the bottom 1 having a central opening 4 which is usually of circular format-ion, as illustrated and which has its free edge serrated as indicated at The rim 2 is formed with a struck-out loop 6 which forms a means of attachment to a chain or the like, which loop by virtue of being struck-out, provides an opening 7.

In the second stage of the manufacture, the blank of Figures 1 and 4 has the free portion 8 of its bottom 1 bent upwardly at right angles to lie parallel to the rim 2. In the final stage of the manufacture, as shown in Figures 3 and 6, the portion 8 is rolled outwardly and upwardly to form a concaveconvex portion the concave side of which faces the rim 2 and the bottom 1, while the convex side forms a seatfor the gem, which latter enables the gem to be self-adjusting when the serrated edge 3 is bent into engagement therewith.

In Figure 7 of the drawings, a number of loops 9 are employed. and in this regard, it will be understood that as many loops as desired may be provided.

From the foregoing, it will be seen that the serrations 5 permit drainage of an of the acid which may be trapped in the ho low circular portion formed between the parts 1, 2 and 8 in which regard the opening 7 will likewise permit drainage of any of the plat-- ing fluid or solution which may be trapped in said parts.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is 1. In a gem setting, a member having a bottom open at its center and having arim extending at right angles to the bottom, the upper edge of the rim being free and formed with serrations, and a gem-engaging member extending from the open center of the bottom toward the rim and having its free edge serrated and engaged with the inner face of the rim at points spaced above the bottom, so that the openings of the serrations communicate with the space above the bottom, and a loop struck out from the inner side of the rim and disposed between the bottom and the serrated edge of the gemengaging member so as to leave an opening opposite the loop which opening also communicates with said space above the bottom.

2. In a gem setting, a member having a bottom open at its center, a rim at the outer portion of the bottom, and a gem engaging element at the inner portion of the bottom extending upwardly and outwardly toward the rim and having a free serrated edge which edge engages the rim at points spaced above the bottom so that the spaces of the serrations communicate with said space above the bottom and provide drainageopem ings for said latter space.

In testimony whereof I have signed my name to this specification.
